Zl'o all whom it may concern:

Be it known that I, Summfll. WmsoN, a citizen of the United States, residing .at Charleston, in thecounty of Kanawha and State of Vest Virginia, have invented cer: tain new and useful Improvements inGrain- Car Doors; and I dodeclare the following to be a full, clear,'and exact description of the invention, such as will enable others.

make and use the same. I I I This inventionrelates to improvei'ocnts in grain car doorsandliasfm its object to provide a car door that will effectively pre vent the accidental escape of'grain or like substances and at the same time may be skilled in the art to which it appertains to readily opened or adjusted to permit the an features of construction, combination 'and arrangemei'it of parts as will be more fully described and particularly pointed out in the appended claim. I

In the accompanying drawings, Figure 1- is'a side view of a portion of a freight car equipped witlr my improved grain car door. Fig. 2 is a similar view 'of the interior of the car. Fig. 3 is a transverse section throughout the car showing the car door swung into a position near the roof. Fig. l is a horizontal longitudinal sectional view on the line it- 1 of Fig. 1, and Fig. 5 is a detail perspective'view of the door.

Like reference numerals indicate corresponding parts throughout the several views. In the accompanying drawings, the nu lneral 1 designates a freight carof the usual or any desired form, and 2 the usual door opening therein. Suitably secured upon the inner side of the freight car 1 near the top of the car is a longitudinally-disposed guidev and suspension track 3', preferably comprising a pair of spaced rails or track sections 4 secured adjacent their upper extremities to a longitudinal bcam5 suspended from a plurality of brackets or beams 6 carried by the earl. Adjacent their lower extremities the track sections 4 are flanged or bent inwardly as at the top of the car. The track sections -l are right augu'larly shaped incross section and have their iuturued portions or flanges forming runways T for the rollers 8 carried ,by door hangers 9. These hangcrsare the T-shapedends of a horizontal connecting bar, or rod 17 as shown more clearly in'Fig."

,The upper extremity of'each hanger 9 projects between the spaced portions or flanges 7 of the track sections 4 and carries a transverse stub shaft .10 on the projecting ends of wlnch latter are rotatably mounted theIr QllersS, as-will be readily understood on reference to-Fig. 3. The lower ends ofthe vertically disposed hangers 9 are bifurcated and carry pivot pins 11 by means .of

which the. upper ends ofi car door supporting bars 12are pivotally mounted in said bifurcated lower extrei'nities ofthe Hangers. The grain car door 13; may be constructed of.

wood metal or any desired material, and

herein shown is I prefera bly'. constructed 7 .of the body plate 14; formedlof a single sheet of metal, having a plurality of angle irons 15 suitably secured at intervals thereto to reinforce andstiften the body port-ion.

The sideedges of the door '13 are bent laterally to stiifen the same, and cooperate with spaced uprightv beams 16 secured to one side of the car and a single beam secured to the other side thereof to prevent the escape of the grain or like material from the interior of the car when the door is closed. The beams or posts 16 also serve to position the grain door in its operative and inoperative position, the side flanges of the car door fitting closely to said posts and overlapping the sides thereof. A suitable latch 18 is provided to retain the car door in its inoperative position adjacent the side of the car.

Adjacent the lower extremity of the body plate 141 of the car door are provided a plurality of spaced wickets 19 to allow the passage of a relatively small quantity of the grain or like material from the car, and said. wickets are adapted to be closed by means of slidable gates or doors 20, which are mounted to slide in vertically-disposed guides secured to the body plate of the car door at each side of the wicket openings, and

preferably are bent or spaced. outwardly from said door to allow the gates 90 to freely slide therein. A- suitable handle or rod 21 is arranged upon the gates 20 to allow the same to be readily moved. I

The supporting bars 12 are preferably formed in s'ectionswith their contiguous end bars threaded'andconnected by means of a turn-buckle 23 whereby the car'door 13 may be vertically adjusted to fit any size door, or

to move the grain door 13 away from the bot-tom of the car to allow the insertion of a conveyer nozzle when it is desired to unload the car.

. In practice, my improved grain door may be longitudinally moved upon the overhead track 3 to an out-of-the-wayplace adjacent .-the 'side of the car while the car is being filled'with grain or the like, and maythen return to its operative-position covering the I doorppening 24 in the freight car, the side flanges of the car overlapping the posts 16 so that the escape of the grain is effectively prevented. hen it is desired to remove the contei'its of the car, one or more of the wickets 20 are opened to allow the grain immediately behind the car door 13 to escape, whereupon the door may swing inwardly upon the pivot pins 11 to a position adjacent the roof of the'car and may be,

heldvin this position by means of a hook or other suitable retaining device 24-. A power-shovel, conveyer nozzle, 0r vlike de-- livering means may then be, inserted into the car to unload the grain therefrom.

From the foregoing description takenin connection with the accompanying drawings,

the construction and operation of the invention Avill'be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention as defined in the appended claim.

Having described my invention, Iclaim:

The combination with the side wall of a car having a door opening, of a horizontally extend ng track of channeled formation arranged above the door opening, adoor, a

horizontal bar having T -shaped ends forming hangers, the latter belng- "ertically disposed and having their upper ends projecting into In testimony whereof I have hereunto set my hand in presence of two subscribing wit nesses. 1
